Multiple problems in installing and running the example [Solutions to all provided in this issue]

[amankapoor]

I was trying to run your example and ran into multiple problems. I fixed all those and was finally able to run the example on port 3846 as intended.

I have described my process stepwise below. There are two approaches, the second one solved the problem, the first one will bring to your notice an issue which I could not fix.

I could not send a pull request with my solution because the solution requires changes inside files in vendor directory. But this is generated by the glide install command. This is the reason why I tried first approach, but it brings to our notice a compatibility issue between latest commit of fosite and fosite-example.

Please have a look.

Approach 1:

1. go get github.com/Masterminds/glide

2. go get -d github.com/ory/fosite

3. C:\Users\Aman Kapoor>go get github.com/ory/fosite-example
   github.com/ory/fosite-example/authorizationserver
   C:\Gospace\src\github.com\ory\fosite-example\authorizationserver\oauth2.go:61: cannot use compose.OAuth2AuthorizeExplicitFactory (type func(*compose.Config, interface {}, interface {}) interface {}) as type fosite.Hasher in argument to compose.Compose:
   func(*compose.Config, interface {}, interface {}) interface {} does not implement fosite.Hasher (missing Compare method)

4. So, I did go get -d -u github.com/ory/fosite-example and it worked. I did it because you suggested it in error on go install  #5 (issue 5)

5. Next step according to you is to change the directory to fosite-example. Did that.

6. And then glide install

7. C:\Gospace\src\github.com\ory\fosite-example>go install

This problem is because of change from ory-am to ory and glide installs this version of your repo ory/fosite@eb9077f

8. I changed glide.yaml file and glide.lock file to have 0.8.0 and 349726028d42f3c60aeefc67aef06f9f907ccf94 (your latest commit when writing this issue)

9. And then I do glide install.

10. Then I do go install, which gives this
    C:\Gospace\src\github.com\ory\fosite-example>go install

github.com/ory/fosite-example/authorizationserver
authorizationserver\oauth2.go:61: cannot use compose.OAuth2AuthorizeExplicitFactory (type func(*compose.
Config, interface {}, interface {}) interface {}) as type fosite.Hasher in argument to compose.Compose:
func(*compose.Config, interface {}, interface {}) interface {} does not implement fosite.Hasher
(missing Compare method)

This error is same as in step 3.

Approach 2 which worked.

Step 1: Do step 6 of approach 1.

Step 2: Find and replace ory-am with ory in all the files under fosite-example folder. (Most of these changes will be done under vendor\github.com\ory\fosite; around 109 files are there)

Step 3: go install
C:\Gospace\src\github.com\ory\fosite-example>go install
github.com/ory/fosite-example/authorizationserver
authorizationserver\oauth2_auth.go:81: not enough arguments in call to oauth2.NewAuthorizeResponse
have ("github.com/ory/fosite-example/vendor/golang.org/x/net/context".Context, fosite.AuthorizeRequester, *openid.DefaultSession)
want ("github.com/ory/fosite-example/vendor/golang.org/x/net/context".Context, *http.Request, fosite.AuthorizeRequester, fosite.Session)
authorizationserver\oauth2_token.go:40: not enough arguments in call to oauth2.NewAccessResponse
have ("github.com/ory/fosite-example/vendor/golang.org/x/net/context".Context, fosite.AccessRequester)
want ("github.com/ory/fosite-example/vendor/golang.org/x/net/context".Context, *http.Request, fosite.AccessRequester)

Step 4: To fix first error in Step 3, I go to this piece of code authorizationserver\oauth2_auth.go:81: and change response, err := oauth2.NewAuthorizeResponse(ctx, ar, mySessionData) to response, err := oauth2.NewAuthorizeResponse(ctx, req, ar, mySessionData)

Step 5: To fix second error in Step 3, I go to this piece of code authorizationserver\oauth2_token.go:40: and change response, err := oauth2.NewAccessResponse(ctx, accessRequest) to response, err := oauth2.NewAccessResponse(ctx, req, accessRequest)

Step 4: go install and it works.

PS: In my first time, when I downloaded this example, I fixed it using second approach only. But then I thought why should we find and replace, and instead I imported the latest commit of fosite, and this way the first approach and its reccuring error came into existence. Your latest fosite code is not working with fosite-example, and I could not fix it. I hope you make necessary changes in latest code to make it work.

I am learning to integrate it in my site that I am building.
